The plant will produce 522 megawatts in total, with 450 of that coming from the natural gas plant, so its renewable portfolio is not exactly robust. But the real gain may be in the ease with which wind and solar are being added to the power grid. Instead of localized solar arrays, or distant behemoth wind farms, the renewable sources are being added to a traditional-style power plant. The varying systems can share a control center as well as connections to the grid, which can make them cheaper and easier to integrate. GE says it can cut the cost of a solar thermal system in half, according to Technology Review.
